Dual SIM phones are basically mobile phones which can accommodate two SIM cards. These SIM cards can be of same mobile operator or different mobile operator. Some dual SIM phones come with a feature of both SIMs active while receiving a call. However in some others when call is being received on one SIM the other SIM is put on hold. The concept of dual SIM is very helpful for many people these days. It provides privacy to the user as you have an option to provide one number for your business purpose and other can be used for personal use. However, the user shares the same telephone list and SMS services which helps the user to feed the number once in the mobile phone and use it with both the SIMs. When receiving a call using the dual SIM mobile, the first come first gets the connectivity and the caller who comes into contact first gets the opportunity to talk regardless of the operator. Advantages of Dual SIM phone over normal phones The dual SIM phone helps you cut down your expenses as you do not require separate phones to maintain two different numbers. The dual SIM phones help you chose different operators, thus providing better connectivity. Dual SIM card phones provide you better privacy as you can dedicate one number for business and the other for your personal circle. If you are a frequent traveler then you can select one SIM for your place of residence and other for the area which you frequently visit. If you have SIMs of two different operators you can decide upon the best offers available between the operators and go for the best plans. If you are a busy person and do not want to be disturbed during the office hours from your personal contacts, then you can put the personal SIM in standby mode. CDMA Phones The Mobile operator uses two technologies for Mobile communication the first one is GSM and the second is CDMA. GSM stands for Global System of Mobile Communication and CDMA stands for Code Division Multiple Access. CDMA technology is considered ideal when you use video streaming and 3G speeds. CDMA phones come with inbuilt SIM cards and these phones cannot be used using a GSM SIM in it. The most prominent advantage of using a CDMA technology is that the mobile phones are available at a cheaper rate and they provide better clarity of speech when compared to GSM mobiles. This phone is ideal for people who use their mobile phones only for making calls especially the business class. This is not very advisable for youths who want numerous multimedia applications. However, in a CDMA phone the call rates are very less when compared to GSM and these phones cannot be easily tampered. The mobile technology has offered various advantages with different mobile phones, so it is the user who has to decide upon his requirements and go for the best mobile phone.
